In order to make the large-size and complex structure of bolted joints closer to the actual engineering situation in the simulation,the finite element simulation analysis method is used to make a horizontal comparison of the simplified modeling methods of such bolted joints.Taking the bolt connection between the drive axle shell and the reducer shell in the chassis structure of a rubber rail train as an example,the solid model of the bolted connection and 19 kinds of simplified models of the bolted connection were established,and the modal analysis and strength analysis were carried out on all the models,and the analysis results of the bolted connection solid model were taken as the benchmark,and the analysis results of the simplified model of each bolt connection were compared horizontally,and the simplified modeling method of simulating the actual working condition of the bolt was obtained more accurately.Based on the results of horizontal comparison,the modeling method of bolt connection of large size and complex structure is proposed,which has practical engineering application significance.
